Paper Abstract

The concept of intermodulated photoacoustics combined with the laser electric resonance spectroscopy for accurate, selective, and sensitive measurements of atmospheric pollution is discussed. Polar molecules such as ammonia, nitric acid, and water vapor adsorb to solid walls and the sampling feedline causing concentration loss and hence erroneous readings. A survey of other novel techniques for studies of ammonia and other gases is given.
